FINGER GRIP FOR VIOLIN BOWS,

Application filed September This invention relates to devices used tofacilitate manoeuvring violin bows and has one of its objects to providean etficient grip capable of being adjusted to fit a persons hand andinsure the fingers and thumb being properly applied to a bow.

It further feature is in the provision of means which not only renderthe handling of a bow effective but also prevent abrasion of the same bythe fingers during long con tinued operation These and. otheradvantages, such as lightness and neatness of appearance, areaccomplished by the novel construction and arrangement of partshereinafter described and shown in the accompanying drawing, formingpart of this disclosure, and in which Figure 1 is a fragmentary sideelevational view of a conventional type of violin bow showing anapplication of the invention,

Figure 2 is an enlarged longitudinal sectional view of the grip asapplied.

Figure 3 is a top plan view of the same.

Figure 4t is a transverse sectional view taken on-line *l-al of Figure3.

Figure 5 is a similar sectional view taken on line 5-5 of Figure Thestick of a violin bow is designated in the drawing by the numeral 10,the same having at its operative end a sliding block 11 to which one endof the stressed, string vibrating element 12, such hair, is secured, theblock being adjusted along the bar by a nut 13, all these several partsbeing of any well known type of construction.

Such bows are usually opcratec by grasping the stick and block betweenthe fingers and thumb when playing an instrument, which becomesexceedingly tiresome if used for a protracted interval of time andeventually wears the parts engaged, causing disfigurement of the same Inthe present invention a thin light tube let, as metal, hard rubber,indurated fiber or other suitable material, loosely fitting the stick10, is formed with taper ends 15 containing longitudinal kerfs 16permitting the extending portions to be sprung inwardly.

Adjacent the tapered portions of the tube are screw threaded portions17, on which are engaged knurled nuts 18, having conical extensions 19adapted to engage the split tapered end elements of the tube, causingthem to contract and grip the stick 10 at 8, 1923. Serial No, 134,153,

any point, preferably adjacent the inner end of the block ii.

The main central portion of the tube 10 is knurled or otherwisecorrugated to provice an efiicient grip and the wall of the tubecontains two or more rows of perforations arranged diametricallyopposite,

A thin spring metal finger guard 21, bent in the shape of an open hook,is formed on a strip presenting opposed transverse arms :2 curved toengage the exterior of the tube, these arms having, near their ends,inreaching nodules die formed and adapted to ena e selectively in any ofthe opposed p is of perforations 20 in the tube;

' From the foregoing it will be seen that the tube is adjustable aroundand lengthwise the bar of the bow and clamped at one or both ends to it;also that the finger guard 21 is readily adjustable on the tube to suit.

In addition to the foregoing a thumb rest may be used, the sameconsisting of an arcuately bent plate having arms 52%, sheared topresent openings 25, the sheared center portions being curved to engagethe tube and provided with inset projections 27, of the naturepreviously described, which engage in the perforations 20, each of theguards being independently adjustable.

Although the foregoing is descriptive of the preferred embodiment of theinvention it will be apparent that minor changes may be made in itsconstruction, without the enercise of invention or conflicting with thescope of the claims hereto appended Having thus described my invention,what l, claim as new and desire to secure by Letters Patent, is

l. A finger grip for violin bows comprisiug a tube for looselysurrounding the stick of the bow, said tube being externally threaded atboth ends, and provided with split cones on the ends thereof, nutshaving screw threaded engagement with the tube to contract each cone,said tube having opposed perforations therein, designed to hold a fingerrest in selected positions on the tube.

2. A finger grip for violin bows compri ing a tube for looselysurrounding the stick of the bow, said tube being externally thread-edat both ends, and provided with split cones on the ends thereof, nutshaving screw threaded engagement with the tube to contract each cone,said tube having opposed perforations therein, a thumb rest havingspring arms en ageable over the tube, and detents carried by said armsengageable in the perforations.

3. A finger grip for violin bows, eoinprising u tube for looselysurrounding the stiek of the bow, ineuns ut the ends of said tube toclamp the same on the bow stick, said tube having opposed perforationstherein, a thumb rest having spring arms engngetiliile over the tube,and detents carried by said arms engageable in the perforations.

4. A finger grip for violin bows comprising a tube for looselysurrounding the stick of the bow, means at the ends of said tube toclamp the Same in fixed position on the bow stick, said tube havingopposed rows of spaced perforations, a hook shaped finger guard havingspring arms to partially encircle said tube, a thumb rest having springarms to partially encircle said tube, and detents on each of said armsfor selectively engaging the spaced perforations.

A finger grip for a violin bow comprising a thin sheet metal tube toloosely surround the stirk of the bow, said tube being externallythreaded back from the ends at both ends, and provided with slits on theends thereof forming flexible tongues, and chuck nuts having screwthreaded engagement with the tube to contract the tongues on the bowstick.

This specification signed this seventh day of September, 1926.
